Minimally Invasive Surgery for Traumatic Fractures in Ankylosing Spinal Diseases.

ABSTRACT: Study Design Retrospective case series. Objective Ankylosing spondylitis (AS) and diffuse idiopathic skeletal hyperostosis (DISH) are two related diseases that significantly increase the risk of unstable spinal fractures from seemingly trivial trauma. Given the older age and higher surgical risk profile of most of these patients, minimally invasive (MIS) approaches to the treatment of such fractures may reduce operative risk and physiologic stress. Methods Eleven consecutive patients with hyperextension thoracolumbar injuries and a diagnosis of AS or DISH admitted to a single level I trauma center between June 2009 and June 2014 were retrospectively reviewed. All patients were treated with MIS stabilization. In addition, the patients were administered the Oswestry Disability Index and EuroQol-5D surveys to evaluate patient-reported outcomes regarding disability and health-related quality of life, respectively. Results Of the 11 patients, 10 were alive at the time of review. The mean follow-up time was 28 months. The average age was 77 years old with a mean body mass index of 34. All patients had severe systemic disease, American Society of Anesthesiologists grade III, with multiple medical comorbidities. Seven segments on average were included in the operative construct. There were no instrumentation failures or nonunions requiring revision surgery. The average postoperative Oswestry disability index was 21.5% (range: 0 to 34%), corresponding to low to moderate disability, and the average EuroQol-5D utility score was 0.77 (range: 0.60 to 1), a similar average postoperative utility value to those published in the literature on elective surgery for degenerative lumbar conditions. Conclusions MIS stabilization, when used on patients with good preoperative neurologic status, can successfully manage spinal fractures in patients with AS and DISH and preserve a favorable postoperative quality of life with limited disability.

Project description:BackgroundTo evaluate therapeutic efficacy of minimally invasive and small incision surgery [minimally invasive surgery (MIS)] in patients with non-flail chest rib fractures through a prospective cohort study.MethodsThis study included 98 patients with non-flail chest rib fractures (≥3 displaced fractures) and 66 patients undergoing MIS served as the experimental group and 32 patients receiving conservative treatment served as the matched control group. Pain index and indicators of pulmonary function [vital capacity (VC); forced expiratory volume in one second (FEV1); peak expiratory flow (PEF)] for the two groups were assessed and compared at the time of admission and before discharge. In addition, duration of pain, time required for the patient to regain the ability to perform daily self-care, mental labor, and moderate-to-severe physical labor, and duration of chest discomfort were measured during long-term follow-up and compared between the two groups.ResultsThere were also no significant differences (P>0.05) in pain index (8 vs. 8) or indicators of pulmonary function (VC: 31.0% vs. 26.5%; FEV1: 29.9% vs. 26.7%; PEF: 15.2% vs. 12.0%) were found between the MIS and conservative treatment groups at the time of admission; while pain index (3 vs. 6), VC (42.1% vs. 35.3%), and FEV1 (44.2% vs. 35.9%) were significantly different between the two groups (P<0.05) but not in PEF (21.2% vs. 19.6%) before discharge. Long-term follow-up showed that duration of pain, time required for the patient to regain the ability to engage in daily self-care, mental labor, and moderate-to-severe physical labor, and duration of chest discomfort in the MIS group were significantly more improved than in the conservative treatment group (P<0.05).ConclusionsMIS was a simple and safe treatment that significantly relieved chest pain and rapidly restored pulmonary function and improved the long-term quality of life of patients with non-flail chest rib fractures of ≥3 ribs with displacement.
